This application claims priority from and incorporates herein by reference the entire disclosure of U.S. Provisional Application Ser. No. 60/316,619 filed Aug. 31, 2001.
The present invention relates to the open service architecture, and more particularly, to a method for aiding applications in migrating from one service enabler to another service enabler in the open service architecture.
In today's network, applications and services are a part of the network operator's domain and are built using intelligent network technology. This approach is excellent for simple mass-market applications, but with the emergence of mobility and the internet protocol, rapid deployment of innovative applications that combine different features and critical enterprise data becomes a challenge.
A number of industrial forums and standardization bodies, such as Parlay and 3GPP, have addressed this challenge and specified APIs (application program interfaces) that serve as an interface between the applications and core networks. The term Open Service Architecture refers to the set of APIs developed by Parlay, 3GPP and ETSI. Within the open service architecture, a basic mechanism exists to which an application within the OSA can subscribe to be notified when a new service capability feature (SCF) becomes available. However, this mechanism provides no indication as to what extent the new SCF is backward compatible with existing SCFs the application is presently using. Thus, there exists a need within the open service architecture for a mechanism for informing an application of the compatibility of new SCFs with existing SCFs.
The present invention overcomes the foregoing and other problems with a system and method for migrating between a first and second service in an open service architecture. A second service registers with an open service architecture framework and responsive thereto a comparison is made between the properties of the second service and the properties of the first service to determine if the second service is backward compatible with the first service. Information concerning whether the second service is backward compatible to the first service is forwarded to at least one application using the first service after the comparison
A more complete understanding of the method and apparatus of the present invention may be obtained by reference to the following Detailed Description when taken in conjunction with the accompanying Drawings wherein:
Referring now to
In the layered architecture shown in
The OSA Framework 55 is a registration and discovery server and enables the openness of the open system architecture and makes it possible to go beyond IN (Intelligent Networks) when it comes to openness, discovery and integration of new features as described below The OSA framework 55 also notifies applications of the addition of new service capability features within the open service architecture 30 The OSA framework 55 provides controlled access to the SCSs 50 which in combination with the distributed technology supports flexibility in application locations in business scenarios. Furthermore, it allows multi membership and even extension of the set of APIs
As shown in
Referring now to
The application 40 contacts the OSA framework 55 and is authenticated at step 105. The application 40 requests at step 110 a discovery interface. The OSA framework 55 returns a reference or pointer to the discovery interface after which the application 40 uses this interface to request the type of SCF 35 and special capabilities needed by the application 40 at step 115. At this time, the OSA framework 55 tracks whether the application 40 is allowed to use the SCF 35 and under what conditions. This is captured in the service level agreement (SLA) between the network operator and the service provider. If the application is allowed to use the SCF 35, the OSA framework 55 returns all IDs of SCFs 35 that could fulfill the needs of the application.
Next, the application 40 selects at step 120 one of the SCFs 35 and signs the so-called Service Agreement. The OSA framework 55 contacts the service factory of the SCS 50 and forwards the conditions under which the application is allowed to use the SCFs 35 at step 125. The SCS 50 creates an SCF 35 instance that is to be used by this application and is also able to check the conditions at step 130, and the framework returns the reference or pointer to the application at step 135. From this point forward the application is authorized to use the SCF 35. While this described registration and discovery process enables the framework to inform an application of variously available SCFs 35 and via the notification interface the potential availability of a new SCS 50, there exists no mechanism for notifying an application of backward compatibility of a new SCF 35 with preexisting SCFs 35 Applications can use the event notification API on the framework 55 to subscribe to events. One example of an event is when a new SCF is made available.
Referring now to
By implementation of the this described extension, seamless migrations or applications between older and newer versions of SCF implementations can be enabled. This would allow an operator to outdate or update an SCF almost automatically. It would further allow an operator to take one SCF out of service for maintenance activities by directing the applications to a backup SCF.
The previous description is of a preferred embodiment for implementing the invention, and the scope of the invention should not necessarily be limited by this description The scope of the present invention is instead defined by the following claims.
